A second cylindrical wire basket or receptacle 18 is suspended in the upper part of thecasing 1 above the basket 16 from the ector 19 having the inwardly curved flange for deflecting the washing .fluid inwardly and downwardl For this purpose, the basket 18 may he provided with an upper rim resting upon the curved flan e of .the said deflector 19.

purpose of readily removing the spray, forming wheel when desired, a handle 28v may be secured to'the hub 24, as shown in Figures 1 and 6.

The washing fluid a adapted tobe ut the machine, the'valve 29 connected to the Ipipe 12 by a valve housing is adapted to operated bygotating a vertical rod 30- (Figure 4) extending to a point near the top of the housingwhere itprojects through the horizontal flan s of a bracket 31secured to the casing 1. e upper end of said rod is provided with a handle 32 (Figure3) whereby the same may be rotated.

In order to securely hold the valve in either open or closed position, the rod 30 is provided with a crank 30, as shown in igure 11, and a sprin 33 connects the crank and the casing 1, t e tendency of the springbeing to snap the rod toopen or closed position, as shown in Figure 12, when the same has been, moved to a point just beyond the dead center position shown in Figure 11.
